Description

Technical Field

[0001] This utility model relates to the field of cleaning mechanism technology, and in particular to a cleaning mechanism for a tobacco storage cabinet. Background Technology

[0002] A tobacco storage cabinet is a container used to temporarily store tobacco raw materials. It typically consists of a cabinet with an open top and a feeding mechanism located above the cabinet. The feeding mechanism moves back and forth along the length of the cabinet, evenly distributing the material falling from above onto a conveyor belt at the bottom of the cabinet. When discharging, the bottom conveyor belt transports the tobacco forward, evenly feeding the tobacco into the conveying equipment of the next process.

[0003] Because tobacco contains oils and contains many impurities and debris, these substances tend to adhere to the conveyor belt and the inner walls of the cabinet after a period of use, thus breeding tobacco insects. Since tobacco storage cabinets are typically quite tall, traditional cleaning methods require manual entry into the cabinet, which is not only difficult and inefficient, but also fails to thoroughly remove residues from corners and crevices. Long-term accumulation of these residues can lead to deterioration of tobacco quality, resulting in cross-contamination of flavors and mold growth. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] Design a cleaning mechanism for a tobacco storage cabinet, including an adsorption component mounted on a fabric mechanism, and a flipping component that folds the adsorption component upward on the outer walls of both sides of the material frame of the fabric mechanism, wherein the adsorption component is fixed on the flipping component.

[0006] The adsorption assembly includes a longitudinal suction pipe located near the inner walls of both sides of the cabinet and a transverse suction pipe located near the upper surface of the conveyor belt. The transverse suction pipe is connected between the two longitudinal suction pipes. Multiple transverse suction ports are provided at the bottom of the transverse suction pipe. Multiple longitudinal suction ports facing the inner wall of the cabinet are provided on each longitudinal suction pipe. A common dust conveying pipe is connected between the upper ends of the two longitudinal suction pipes. One end of the dust conveying pipe extends to the outside of the cabinet and is connected to a negative pressure adsorption machine.

[0007] Preferably, the flipping assembly includes a rotating shaft rotatably mounted on both sides of the material frame, a longitudinal flipping rod connected to the other end of each rotating shaft, a rotating block connected to each rotating shaft, a spring telescopic sleeve rod and a power telescopic rod connected to both ends of the rotating block respectively, the fixed end and telescopic end of the spring telescopic sleeve rod and the power telescopic rod are respectively hinged to the material frame and the rotating block, and each of the longitudinal dust suction pipes is fixedly connected to the corresponding longitudinal flipping rod through a connecting sleeve.

[0008] Preferably, the spring telescopic sleeve includes a fixed sleeve and a telescopic spring, a limiting plate, and a telescopic rod arranged sequentially inside the sleeve. The limiting plate is slidably connected to the inner wall of the fixed sleeve, and the telescopic rod and the fixed sleeve are respectively hinged to the rotating block and the outer wall of the material frame.

[0009] Preferably, the power telescopic rod is an electric actuator or a cylinder, with its telescopic end and the fixed end of the cylinder body respectively hinged to the rotating block and the outer wall of the material frame.

[0010] Preferably, a connecting rod is provided between the two longitudinal flipping rods.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. By using a combination of vertical and horizontal suction pipes, the system targets the inner walls of the cabinet and the bottom conveyor belt—two key areas prone to contaminant buildup—for cleaning. The vertical suction nozzles face the inner walls of the cabinet, while the horizontal nozzles are positioned close to the upper surface of the bottom conveyor belt. Combined with negative pressure adsorption, this effectively removes tobacco grease, impurities, and debris, preventing contaminants from accumulating in corners and crevices. This reduces the risk of tobacco insect infestation at its source, ensuring the quality of the tobacco raw materials and preventing issues such as cross-contamination and mold growth.

[0013] 2. The flipping component can drive the adsorption component to fold upward flexibly. When the tobacco storage cabinet is in the process of feeding or discharging, the adsorption component can be stored in a position that does not affect the tobacco conveying path and the movement of the feeding mechanism. This completely solves the problem that traditional fixed cleaning devices are prone to interfering with the production process, ensuring the continuity of tobacco storage cabinet production and eliminating the need for frequent shutdowns for cleaning.

[0014] 3. This application eliminates the need for manual entry into the tall filament storage cabinet. Automated cleaning is achieved through the coordinated operation of the negative pressure adsorption machine and the flipping component, reducing the intensity of manual labor and avoiding the safety risks of operating in confined spaces for personnel, thus meeting the requirements for safe production.

[0015] 4. The power telescopic rod and the spring telescopic sleeve in the flipping assembly work together to provide a stable driving force for the flipping of the adsorption assembly, and also to buffer the impact force during the flipping process, reduce component wear, and extend the service life of the equipment.

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example 1

[0022] A cleaning mechanism for tobacco storage cabinets, such as Figures 1 to 3 As shown, it includes an adsorption component mounted on the fabric mechanism 9. On the outer walls of both sides of the material frame 8 of the fabric mechanism 9, there are flipping components that fold the adsorption component upwards. The adsorption component is fixed on the flipping component. The adsorption component is fixed on the rear side of the flipping component.

[0023] The adsorption assembly includes a longitudinal suction pipe 2 located near the inner walls of both sides of the cabinet 1 and a transverse suction pipe 14 located near the upper surface of the conveyor belt 13. The transverse suction pipe 14 is connected between the two longitudinal suction pipes 2. Multiple transverse suction ports are provided at the bottom of the transverse suction pipe 14. Multiple longitudinal suction ports facing the inner wall of the cabinet 1 are provided on each longitudinal suction pipe 2. A common dust conveying pipe 11 is connected between the upper ends of the two longitudinal suction pipes 2. One end of the dust conveying pipe 11 extends to the outside of the cabinet 1 and is connected to a negative pressure adsorption machine.

[0024] During cleaning operations, the negative pressure adsorption machine starts to generate negative pressure, which is transmitted to the longitudinal suction pipe 2 and the transverse suction pipe 14 through the dust conveying pipe 11. The longitudinal suction pipe 2, located near the inner walls on both sides of the cabinet 1, has its longitudinal suction port precisely aligned with the inner wall of the cabinet 1 to suck up tobacco grease, impurities, and debris adhering to the inner wall. The transverse suction pipe 14, located near the upper surface of the conveyor belt 13, has its bottom transverse suction port close to the bottom surface of the conveyor belt to adsorb tobacco-related pollutants remaining on the conveyor belt 13. When cleaning is not required, such as when the tobacco storage cabinet is in the process of feeding or discharging, the flipping component can drive the adsorption component to fold upwards, preventing the adsorption component from interfering with the normal operation of the tobacco storage cabinet.

[0025] The flipping assembly includes a rotating shaft 10 rotatably mounted on both sides of the material frame 8, a longitudinal flipping rod 4 connected to the other end of each rotating shaft 10, a rotating block 6 connected to each rotating shaft 10, a spring telescopic sleeve rod 7 and a power telescopic rod 5 connected to both ends of the rotating block 6 respectively. The fixed end and telescopic end of the spring telescopic sleeve rod 7 and the power telescopic rod 5 are respectively hinged to the material frame 8 and the rotating block 6. One end of the rotating shaft 10 extends to the outside of the material frame 8 and is connected to the rotating block 6. Each longitudinal dust suction pipe 2 is fixedly connected to the corresponding longitudinal flipping rod 4 through a connecting sleeve 3.

[0026] The flipping assembly uses the rotating shaft 10 as its core rotating component. When the adsorption assembly needs to be flipped, the power telescopic rod 5 actuates, and its telescopic end pulls the rotating block 6 hinged to it. Since the rotating block 6 is connected to the rotating shaft 10, the rotation of the rotating block 6 will drive the rotating shaft 10 to rotate synchronously, thereby causing the longitudinal flipping rod 4, which is connected to the other end of the rotating shaft 10, to rotate accordingly. Furthermore, since the longitudinal suction pipe 2 is fixed to the longitudinal flipping rod 4 through the connecting sleeve 3, the rotation of the longitudinal flipping rod 4 drives the adsorption assembly to flip. During the operation of the power telescopic rod 5, the spring telescopic sleeve 7 will extend and retract accordingly. On the one hand, this buffers the rotation of the rotating block 6, preventing excessive rotation speed from damaging the adsorption assembly; on the other hand, after the power telescopic rod 5 stops operating, it helps maintain the stable position of the rotating block 6 and the adsorption assembly.

[0027] The spring telescopic sleeve 7 includes a fixed sleeve and a telescopic spring, a limiting plate, and a telescopic rod arranged sequentially inside the sleeve. The limiting plate is slidably connected to the inner wall of the fixed sleeve, and the telescopic rod and the fixed sleeve are respectively hinged to the outer walls of the rotating block 6 and the material frame 8.

[0028] The power telescopic rod 5 is an electric push rod or a cylinder, and its telescopic end and the fixed end of the cylinder body are respectively hinged to the outer wall of the rotating block 6 and the material frame 8.

[0029] A connecting rod 12 is provided between the two longitudinal flipping rods 4. The connecting rod 12 enables the synchronous movement of the two longitudinal flipping rods 4, thereby allowing the longitudinal suction pipes 2 on both sides to flip synchronously with the longitudinal flipping rods 4. At the same time, the connecting rod 12 can enhance the overall rigidity of the two longitudinal flipping rods 4 and prevent the longitudinal flipping rod 4 on one side from bending and deforming due to uneven force.

[0030] The working principle of this utility model is as follows: When the tobacco storage cabinet needs cleaning, firstly, the power telescopic rod 5 is activated, extending its telescopic end to push the rotating block 6 to rotate around the rotating shaft 10. Simultaneously, the spring telescopic sleeve 7 retracts to assist, causing the longitudinal tilting rod 4 to rotate downwards. At this time, the telescopic rod retracts inwards along the fixed sleeve, compressing the telescopic spring. The elastic force buffers the rotational speed of the longitudinal tilting rod 4, ensuring the adsorption assembly is lowered smoothly. When the longitudinal suction pipe 2 is close to the inner walls of both sides of the cabinet 1 and the transverse suction pipe 14 is close to the upper surface of the conveyor belt 13, the power telescopic rod 5 stops operating.

[0031] After the adsorption components are in place, the negative pressure adsorption machine is activated, creating a negative pressure environment within the longitudinal suction pipe 2 and the transverse suction pipe 14 via the dust conveying pipe 11. The longitudinal suction port on the longitudinal suction pipe 2 draws in the tobacco grease, impurities, and debris adhering to the inner wall of the cabinet 1; the transverse suction port at the bottom of the transverse suction pipe 14 is close to the bottom surface of the conveyor belt, adsorbing residual tobacco debris and dust on the conveyor belt 13. The pollutants are collected through the longitudinal suction pipe 2 and the transverse suction pipe 14 and discharged through the dust conveying pipe 11 to the outside of the cabinet 1, achieving cleaning of the key areas of the tobacco storage cabinet. During the cleaning process, the cloth-laying mechanism 9 can move slowly along the length of the cabinet 1, driving the adsorption components to thoroughly clean the inner wall and conveyor belt 13 along the entire length of the cabinet 1.

[0032] After cleaning, the negative pressure adsorption machine continues to run to ensure that residual pollutants in the pipeline are completely discharged. After the adsorption machine is turned off, the power telescopic rod 5 moves in the opposite direction, the telescopic end retracts, and pulls the rotating block 6 to rotate in the opposite direction; the spring telescopic sleeve 7 extends in coordination, driving the cleaning component to fold upward and return to a position that does not affect the normal operation of the wire storage cabinet, thus completing one cleaning process.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
